Microcode Update

What is a microcode update?

As there are no drivers for processors, Intel offers the possibility from the P6 family (Pentium Pro)

on to update the command set (microcode) of the processor. This enables minor errors to be

corrected and the performance to be increased.

To guarantee the best possible performance and error-free operation, Intel recommends updating

the microcode for every new processor. Intel refers to the use of the processor without microcode

updates as operation outside the specifications.

Safety for processor on Fujitsu Siemens Computers mainboards

If the processor uses an old or incorrect microcode, error-free operation cannot be ensured. Fujitsu

Siemens Computers has therefore implemented a function on its mainboards that interrupts the

booting process if no suitable microcode is available for the installed processor. The output error

message is

Patch for installed CPU not loaded. Please run the bios flash update

diskette.

This message appears until the microcode update has been carried out. If the computer is

nevertheless operated without a microcode update, error-free operation is not ensured.

When should a microcode update be carried out?

A microcode update should be carried out after the installation of a new processor.

In contrast to the BIOS update, only an updated version of the processor command set is stored.

The system BIOS remains unaffected by this.
